Granted: 1993-12-07
Abstract: ABSTRACT   A method and apparatus for precisely varying the display rate of computer generated graphic images. These images are generated by a computer system. The images are made up of a plurality of individual cells. Each cell is a picture of the object at a different point in time. With the present method, the user inputs the desired display rate into the computer system. The computer then converts this display rate into a vector located in the first quadrant of an x,y coordinate system. In this system, the x-axis represents increasing time and the y-axis represents cell number. The vector is displaced away from the x-axis through an angle. Theta is a predetermined function of the previously entered display rate. The first cell in the image is displayed, and the computer waits for a fixed interval of time. After this wait period, the computer uses a simple algorithm to check the height of the vector above the x-axis. If the vector is above a specified height, then the next cell is displayed. Otherwise, the computer displays the current cell for an additional fixed interval of time, and then repeats the check of the vector height. The steps of displaying the image and checking the height of the vector above the x-axis is repeated for all cells in the image. If display is to continue after this point, the cells are shown over again in the same order.

Title: Decontamination and/or surface treatment of metals
Inventor: DUBE GHYSLAIN
IPC: C23G5/00
Filed: 1990-07-20
Granted: 1996-12-17
Abstract: A process of decontaminating metal (especially aluminum or aluminum alloy) scrap contaminated with organic material is provided.  The process involves heating the scrap in a fluidized bed of solid particles fluidized by a fluidizing gas to a decontaminating temperature high enough to consume the organic material but below the melting point of the metal. The heating step is carried out in the presence of a protective material which protects the aluminum or aluminum alloy against substantial oxidation while the scrap is held in the bed at the decontaminating temperature.  Preferred protective materials include organic and inorganic fluorine-containing compounds.  The process is particularly effective for the treatment of aluminum alloys containing magnesium, which are especially susceptible to oxidation.  Scrap decontaminated in this way can be subjected to conventional metal recovery processes, e.g. metal melting, and provide high recovery rates of the metal.  The process of the invention can also be used for protecting metal (particularly aluminum and alloys thereof) against excessive oxidation during heat treatments other than decontamination. The invention also relates to the treatment of briquettes of compacted scrap without the need for prior shredding or grinding.

Title: Electrically controlled shutoff valve and use of the latter
Inventor: HOCHSTRASSER FERDINAND
IPC: F16K31/40
Filed: 1990-10-24
Granted: 1995-02-21
Abstract: The mixing fitting (10) has a shutoff valve (22) for hot water and a shutoff valve (24) for cold water. These shutoff valves (22, 24) are constructed as dia-phragm valves and each have an auxiliary valve (62, 62') provided in the pilot control space  (50).  To operate these auxiliary valves (62, 62'), permanent magnets (76) are provided which can be swivelled about the axle (80') into and out of the range of action on the closure elements (64) of the auxiliary valves (62, 62'). To open the shutoff valves  (22, 24), the swivel body (78) is swivelled by means of the drive (94) with the permanent magnets  (76)  into the region of the closure elements (64), by which means the latter are pulled toward the permanent magnets (76) with the auxiliary valve (62, 62') opening. The pressure in the pilot control space (50) drops and the shutoff valve (22, 24) is opened by the closure part (44) being lifted from the valve seat (40). If the permanent magnets (76) are again swivelled out of the range of action on the closure elements (64), the latter  close  the  auxiliary valves  (62,  62'),  which results in the pressure in the pilot control space rising again due to the passage (52). The closure part (44) again comes to rest on the corresponding valve seat. The shutoff valve (22, 24) is thus closed.
